Kurzfassung

Medium resolution SAR satellite data have been widely used for water and flood mapping in recent years. Since the beginning of 2008 high resolution radar data with up to one meter pixel spacing of the TerraSAR-X satellite are operationally available. The improved ground resolution of the system offers a high potential for water detection. However, image analysis gets more challenging due to the large amount of image objects that are visible in the data. Water body detection methods are reviewed with regard to their applicability for TerraSAR-X data. The concept for the water body detection in the scope of the TanDEM-X mission is shown. Finally flood detection approaches for rapid disaster mapping are presented in this paper along with a flood map example.
